[PATCH 3/4] drm/amd/display: pass panel instance in dirty rect message

[sunpeng.li at amd.com]

From: David Zhang <dingchen.zhang at amd.com>

[why]
DMUB FW uses OTG instance to get eDP panel instance. But in case
of MPO multiple pipe indexes are passed to updated the same panel.
The other OTG instance passed would be ignored causing in DMUB not
acknowledging the messages.

[how]
Add panel instance to dirty rectangle data and cursor update data
structures and pass to DMUB.
